About 45,400 people have registered to participate in a $641 million settlement to compensate individuals affected by the Flint water crisis, but it is not a final tally, according to a court filing released Wednesday. Thousands of electronic and mailed registration forms are still being reviewed, although some of them appear to be redundant, case special master Deborah Greenspan said in the filing. The claims administrator expects to receive more registrations from Flint's roughly 95,000 residents with postmarks of March 29 or before. The claims administrator "estimates that it will take at least a week to complete the review and additional time after that to determine the number of duplicative registrations," Greenspan said.
